Study Pinpoints Source of Banned Gas That Saps Ozone Layer: Eastern China

Rogue emissions of a gas that harms the ozone layer are coming from eastern China, primarily from two heavily industrialized provinces, an international team of researchers said Wednesday. The findings confirm what many scientists, environmental groups and policymakers had suspected after an initial study a year ago reported new global emissions of the gas, CFC-11, but could only locate the source generally as East Asia. It also confirms the results of several investigations, including one by The New York Times, which found evidence that factories in Shandong, one of the provinces specified in the study, were still making or using the gas to manufacture foam insulation.
